Let the expression we will add be "A", thus we can write:

We can use the distributive property on the right hand side and then use a bit algebra to solve for "A". The distributive property is shown below:

Let's do the algebra. The steps are shown below:

Thus, we need to add 4x + 2 to "5x + 7" to make it equal to "9(x+1)".

The correct answer is:

The solution of given inequality 3-|4-n| >1 is 2<n<6.So option D is correct.

An inequality is a relation that compares two numbers or other mathematical expressions in an unequal way. The majority of the time, size comparisons between two numbers on the number line are made.

The given inequality is 3 - |4-n| > 1

Since |4-n| is the absolute value

Absolute value describes the distance from zero that a number is on the number line, without considering direction. The absolute value of a number is never negative.

So ( 4-n ) may be negative or positive.

For positive value of ( 4-n )

3-( 4-n ) > 1

3-4+n>1

n>2

For negative value of (4-x)

3+( 4-n )>1

3 + 4-n >1

7 - n > 1

-n> 1 -7

-n > -6

n < 6

Hence, 2 < n < 6 i.e. option D is the solution to the inequality 3-|4-n| >1.

For the given  polynomial function f(x) =(x+9)(x-5)(x+7) the real number solutions are x = -9, -7,5.

As given in the question,

Given polynomial function :

f(x) =(x+9)(x-5)(x+7)

Real number solutions for the given polynomial function

f(x) =(x+9)(x-5)(x+7)

Values for which f(x) =0

0= (x+9)(x-5)(x+7)

Equate all the value to zero we get,

⇒ (x+9) =0 , (x-5) =0 , (x+7) =0

⇒ x = -9 , 5, -7

For x= -9 , 5, -7  polynomial function f(x) =(x+9)(x-5)(x+7) value is equal to zero.

Therefore, for the given polynomial function f(x) =(x+9)(x-5)(x+7) the real number solutions are x = -9, -7,5.

Let's analyze the example of the ratio of 9 to 15.

This ratio helps us to compare those two numbers. We can express it in different ways:

The pairs of whole numbers which have 40 as a sum is 21

What is Whole numbers ?

All natural numbers and 0 are included in the category of whole numbers. They are a subset of real numbers, which exclude negative numbers, decimals, and fractions. Whole numbers include counting numerals as well.

For finding the term we use Arithmetic Progression which is :

a(n) = a + (n - 1)d

where,

a(n)  = the nᵗʰ term in the sequence

a = the first term in the sequence

d = the common difference between terms

Given,

The first term a₁ = 0

The common difference d = 1 (from 1 - 0, 2 - 1, etc.)

The last term aₙ = 20

Putting the values in the formula we get,

20 = 0 + (n - 1)1

20 = 0 + n- 1

20 + 1 = n

21 = n

Hence, there are 21 pairs of whole numbers that have a sum of 40

The value of x is given by 6 units and the value of TV is given by 7 units.

A circle may be defined as a closed loop which has a fixed point around which the loop is made called the center and the fixed distance from the center of the circle to its periphery is known as the radius of the circle. We are given a circle with center at Z. In the circle QR and ST are the chords such that QR = ST = 14 that is both are of equal length, and we know that equal chords are at equal distance from the center. Therefore,

VZ = UZ

23 = 3x + 5

18 = 3x

=> x = 18/3

=> x = 6 units.

Now, we also know that perpendicular drawn from center of the circle to the chord bisects the chord. Thus,

TV = (1/2)×ST

TV = (1/2)×14

TV = 7 units.

Using proportional relationships, it is discovered that they will cover 32 miles overall by walking 12 laps and running 20 laps.

For the second issue, the appropriate response is:

Brown 12 10 14 30

Green 20 25 35 75

Total 32 35 49 105

What is a direct proportional relationship?

In a direct proportional connection, the output variable is determined by multiplying the input variable by the proportionality constant, k, as in the example below:

y = kx.

For the first question, we have that out of a total distance of 8 miles, they:

Walk 3/8 of the distance.

Run 5/8 of the distance.

Hence the proportional relationships for the distances are given as follows:

Walked = 3/8 x Total Distance.

Ran = 5/8 x Total Distance.

For a total distance of 32 miles, the distances walked and ran are given as follows:

Walked: 3/8 x 32 = 3 x 4 = 12 miles = 12 laps.

Ran: 5/8 x 32 = 5 x 4 = 20 miles = 20 laps.

For the second question, we have that the table has to following the given ratios of the first row to the second row, with the third row being the sum of the first two rows, hence the third table is correct.

I believe that Americans have just the right amount of freedom.

The First Amendment protects our freedom of speech and association, so the government cannot stop us from writing or speaking what we choose. We also have the right to create clubs and groups and participate in protests and rallies.

As long as you don't "materially and substantially" interrupt classrooms or other school activities, you have the right to voice your ideas. School administrators can disperse you if you stage a demonstration on the steps of the building and block the entrance. Additionally, they may be able to prevent you from using words that they deem to be "vulgar or indecent."

average rate of change = 23

Step-by-step explanation:

the average rate of change of f(x) in the closed interval [ a, b ] is

[tex]\frac{f(b)-f(a)}{b-a}[/tex]

The computation of the expression using the fewest possible terms is D. 21 over 40 times t plus positive 22

It should be noted that on Mathematics, an expression is used to show the relationship between the variables that are given or illustrated.

In this case, the expression given is illustrated as three fourths times t minus 5 plus two fifths times t end quantity minus quantity five eighths times t plus 17 end quantity.

This will be:

= (3/4t - 5 + 2/5t) - (5/8t + 17)

= (15/20t + 8/20t - 5) - (5/8t + 17)

= 23/20t - 5 - 5/8t + 17

= 46/40t - 5 - 25/70t + 17

ANSWER

EXPLANATION

First, we have to draw horizontal lines at the minimum and maximum heights. These are 10 feet and 210 feet, respectively.

Then, we calculate the midline,

And we have to draw this line too.

As mentioned, the period is the time it takes to do one revolution, which this wheel makes in 90 seconds. Thus, the period is 90 seconds and the first cycle starts at t = 0 and ends at t = 90 s,

Then, we know that the graph is sinusoidal, so we have to draw the first cycle - note that if the period is 90 s, the graph must intersect the midline at 45 seconds,

And finally, draw another cycle just like the first one.

A function is said to be an odd function if its graph is symmetric with respect to the origin.

Examples of odd functions are;

The odd functions are; C, D E, H, J, K, N

By using trigonometric relations for right triangles, we will see that the height of the tower is 81.92 meters.

First, we know that a pole with a height of 3.3m casts a shadow of 1.48m. We can see the height of the pole and the length of the shadow as the legs of a right triangle, with that, we can get the angle at which the sun hits the pole (this angle is such that the height will be the adjacent cathetus).

Using the trigonometric relation:

tan(a) = (opposite cathetus)/(adjacent cathetus)

We can get:

a = Atan( (opposite cathetus)/(adjacent cathetus))

With taht we can find the angle, where:

opposite cathetus = 1.48m

adjacent cathetus) = 3.3m

Then:

a = Atan(1.48/3.3) = 24.16°

For the tower that angle will be the same one, and again, the height is the adjacent cathetus and the shadow the opposite cathetus, so we can write the same equation than before:

tan(24.16°) = shadow/height.

Solving that for the height we get:

height = shadow/tan(24.16°) = 36.75m/tan(24.16°)  = 81.92m

The height of the tower is 81.92 meters.
